Question about Pontiac Grand Prix

1 Answer

Especially in colder weather when the road is rougher and the suspension is stiffer it feels like you have no control over your rear end. The road I drive is like a washboard and it feels like my rear end is just floating all over the road. Like it is just bouncing around. The bushings are not bad, probably haven't ever been replaced but look ok yet. Both mechanics I've talked to tell me that it drives like any other grand prix they have driven. I find it hard to believe that all of them drive this badly. It is scary to drive sometimes. Any thoughts are greatly appreciated!

May be time for new rear struts & spring assemblies. It doesn't say what year or mileage but by the sounds of it, it certainly resembles worn shocks/struts at least. Sometimes it's just as cheap & safer to replace strut & spring assembly now days.

2007 ford sport trac at high speeds it feels like my front end is walking all over the road but no shimmy in my steering wheel and goes straight tires look ok rotated tires problem still there.


could be from worn tie rod ends, suspension ball joints , worn suspension rubbers and failing shock absorbers
take it to an accredited suspension service center for a complete check including the rear end as the front floating sensation could be from a problem rear end suspension set up and shock absorbers
I am well aware that every tire shop says rotate tires but in reality you just move a problem tire from one corner to the other, fail to see a wear problem develop in the tires ( indicates alignment or tire case problem) and costs 4 tires at a time instead of 2 which is not really economical as well
consider this front drive cars wear out front tires at the rate of 3 to rear tires 1 and I think you get the picture (rear drive cars rear tires 2 to front 1) or if there is a case problem with a tire it is lost in the rotation process and becomes dangerous on the road

I feel unstable going at moderate speed around a corner. it doesnt feel like it hugs the road. is this because it is base GXE model?


in stability in corners can be from several reasons
The first is the quality of tires in use as all stability feelings are generated by the tire profile, tire pressure and side wall profile and the quality of the tire (for example a 195 -75 r15 tire will feel loose compared to a 195-25r15 tire which has small side wall dimension and so sits better in the corners )
Next is the condition of the shock absorber, worn out , old or not of good quality manufacturer ( shock absorbers are design to take the rebound out of springs and suspension movement and if they are of inferior quality or worn out , instead of allowing the body to roll slowly , it feels like it will fall over )
Next is the use of a stabilizer bar front and rear as this is what keeps the car feeling level on the road when cornering ( if the stabilizer bar is too thin in section it torques to easily and the movement of the center of gravity is not properly controlled and so the body leans too much instead of sitting flat)
Suspension parts , ball joints , struts , steering rod ends , bad rubbers all add to a bad feeling
another reason could be a wheel alignment or loose wheel bearings ( steering tends to dart and feel out of control when cornering)
Many cars are designed with "soft" suspension to enhance the driving experience but this type of suspension will give the feeling of uncertainty when cornering ( like being on a water filled mattress)
To get a cost of the suspension up grade you first have to know what is the reason for the bad feeling
I would suggest a full safety inspection by an accredited specialist suspension shop ( Pedders or the like ) and then a quote on the modifications that will improve drivability and cornering
a job done professionally will be a safe and legal job

The rear end on my GTP sways from side to side,what could be causing it?


if this is a feeling like the wobble of a ducks rear end as it walks, it will be belt separation of the rear tyre/s ( bridgestone tyres are bad for it after a few years or partially worn tyre)
this is most noticeable at low road speeds
other than that have the rear suspension bushes and mounting bolts checked

What is causing my front end to ride rougher than it use to?


Potholes are brutal on vehicles, you have springs for sure even if you don't have shocks and they weekend with time and the road, they are Not that hard to replace if you have a spring compressor removal tool....

Loose front end


A vague feeling from the front isn't good news and might be anything even something at the rear so check everything - if it is possible for it to wear it should have a good shake or be tested with a prybar.

I am wondering if the wheel alignment has been checked since the front overhaul...

One common but frequently overlooked thing that causes a car to be unhappy on the road is tyre mismatch - this usually manifests as a vague feeling with the car seeming to choose it's own line depending on the road surface and hopping around a little especially when driving along white road markings or the seams of road repairs.

There is a bar hanging from behind the rear passenger side wheel and in drive the car feels like someone is rear ending you and in reverse the bar drags and the air suspension just goes flat


Don't drive it until you have someone look at it. If it's
part of the suspension, it would be too dangerous to
drive on public roads. It sounds like the rear stabilizer
bar has dropped.Good luck.

You said stock height, does that mean you have stock suspension aswell? If I were you I would install stiffer shocks all the way around and add or replace the stock front stabilizer bar with a stiffer one. You may also consider installing more rigid leaf springs in the rear.

Hope this helps
